.Sh DESCRIPTION
.Fn OCSP_RESPONSE_new
allocates and initializes an empty
.Vt OCSP_RESPONSE
object, representing an ASN.1
.Vt OCSPResponse
structure defined in RFC 6960.
.Fn OCSP_RESPONSE_free
frees
.Fa resp .
.Pp
.Fn OCSP_RESPBYTES_new
allocates and initializes an empty
.Vt OCSP_RESPBYTES
object, representing an ASN.1
.Vt ResponseBytes
structure defined in RFC 6960.
Such an object is used inside
.Vt OCSP_RESPONSE .
.Fn OCSP_RESPBYTES_free
frees
.Fa respbytes .
.Pp
.Fn OCSP_BASICRESP_new
allocates and initializes an empty
.Vt OCSP_BASICRESP
object, representing an ASN.1
.Vt BasicOCSPResponse
structure defined in RFC 6960.
.Vt OCSP_RESPBYTES
contains the DER-encoded form of an
.Vt OCSP_BASICRESP
object.
.Fn OCSP_BASICRESP_free
frees
.Fa bs .
.Pp
.Fn OCSP_RESPDATA_new
allocates and initializes an empty
.Vt OCSP_RESPDATA
object, representing an ASN.1
.Vt ResponseData
structure defined in RFC 6960.
Such an object is used inside
.Vt OCSP_BASICRESP .
.Fn OCSP_RESPDATA_free
frees
.Fa respdata .
.Pp
.Fn OCSP_RESPID_new
allocates and initializes an empty
.Vt OCSP_RESPID
object, representing an ASN.1
.Vt ResponderID
structure defined in RFC 6960.
Such an object is used inside
.Vt OCSP_RESPDATA .
.Fn OCSP_RESPID_free
frees
.Fa respid .
.Pp
.Fn OCSP_response_create
creates an
.Vt OCSP_RESPONSE
object for
.Fa status
and optionally including the basic response
.Fa bs .
.Pp
.Fn OCSP_response_status
returns the OCSP response status of
.Fa resp .
It returns one of the values
.Dv OCSP_RESPONSE_STATUS_SUCCESSFUL ,
.Dv OCSP_RESPONSE_STATUS_MALFORMEDREQUEST ,
.Dv OCSP_RESPONSE_STATUS_INTERNALERROR ,
.Dv OCSP_RESPONSE_STATUS_TRYLATER ,
.Dv OCSP_RESPONSE_STATUS_SIGREQUIRED ,
or
.Dv OCSP_RESPONSE_STATUS_UNAUTHORIZED .
.Pp
.Fn OCSP_response_status_str
converts one of the
.Fa status
codes returned by
.Fn OCSP_response_status
to a string consisting of one word.
.Pp
.Fn OCSP_response_get1_basic
decodes and returns the
.Vt OCSP_BASICRESP
object contained in
.Fa resp .
It is only called if the status of a response is
.Dv OCSP_RESPONSE_STATUS_SUCCESSFUL .
.Pp
.Fn OCSP_basic_sign
signs the OCSP response
.Fa bs
using the certificate
.Fa signer ,
the private key
.Fa key ,
the digest
.Fa dgst ,
and the additional certificates
.Fa certs .
If the
.Fa flags
option
.Dv OCSP_NOCERTS
is set, then no certificates will be included in the request.
If the
.Fa flags
option
.Dv OCSP_RESPID_KEY
is set, then the responder is identified by key ID
rather than by name.
.Sh RETURN VALUES
.Fn OCSP_RESPONSE_new
and
.Fn OCSP_response_create
return a pointer to an
.Vt OCSP_RESPONSE
object or
.Dv NULL
if an error occurred.
.Pp
.Fn OCSP_BASICRESP_new
and
.Fn OCSP_response_get1_basic
return a pointer to an
.Vt OCSP_BASICRESP
object or
.Dv NULL
if an error occurred.
.Pp
.Fn OCSP_RESPBYTES_new ,
.Fn OCSP_RESPDATA_new ,
and
.Fn OCSP_RESPID_new
return a pointer to an empty
.Vt OCSP_RESPBYTES ,
.Vt OCSP_RESPDATA ,
or
.Vt OCSP_RESPID
object, respectively, or
.Dv NULL
if an error occurred.
.Pp
.Fn OCSP_response_status
returns a status value.
.Pp
.Fn OCSP_response_status_str
returns a pointer to a static string.
.Pp
.Fn OCSP_basic_sign
return 1 on success or 0 on failure.
